Strontium Iodate Formula

The chemical formula for strontium iodate is Sr(IO3)2. This indicates that each unit of strontium iodate contains one strontium ion (Sr2+) and two iodate ions (IO3-). The strontium ion has a charge of +2, while each iodate ion carries a charge of -1.

The compound is formed through the reaction of strontium hydroxide (Sr(OH)2) with iodic acid (HIO3), which results in the formation of water (H2O) and strontium iodate. The balanced chemical equation for this reaction is:

Sr(OH)2 + 2HIO3 → Sr(IO3)2 + 2H2O

Strontium iodate is a white crystalline solid that is sparingly soluble in water. It is commonly used as a precursor for the synthesis of other strontium-containing compounds, as well as in the production of pyrotechnic materials and as an oxidizing agent in organic chemistry reactions.

The compound adopts a tetragonal crystal structure, with the strontium ions located at the corners of the unit cell and the iodate ions occupying the central positions along the edges. The lattice parameters for strontium iodate are a = b = 0.742 nm and c = 0.671 nm.
